is that a 5" pipe? that's huge! Where are you going to run it out back? big single exit out the side?

great work man

No it's 4":Dand I still need to find a muffler then I plan routing it behind the rear tire above the spring and pointing down somewhat.

Thanks.

What kind of sound are you after? Also, do you want it to be somewhat loud and aggressive, or noticeable but quiet?

Leaning towards the noticeable but quiet. I had a straight piped 02 24 valve and it was enough to drive a person bonkers, and on my 91 it's a stock 3" with a magnaflow and it's great in the cab and still sounds great when it pulls away.

I will be going to look at this one today and probably get it since it will save me about 150.00

In that case, I'd recommend the Hushpower muffler. They are a little on the pricey side, but well worth it. No drone inside the cab but when you're outside, you'll hear a nice tone from the engine.

I like the fact that it's made by Flowmaster:D

This is from there site and the price is in line with Magnaflow and Aero.
Thanks again.

Hushpower Pro Series mufflers are a result of our our continuing endeavour to bring the latest in performance and sound control technology to the street and race track, Flowmaster, Inc is proud to introduce its newest line of performance Pro Series mufflers. These round-cased mufflers deliver ground breaking sound control while delivering maximum power and exhaust system efficiency. The Hushpower Pro Series mufflers work on all applications ranging from street trucks, diesel "pullers" and RV "pushers" to every class of racing on dirt or asphalt.
During development, at the dyno and track, the new Hushpower Pro Series mufflers consistently delivered performance that is equal to or surpasses open pipe systems, while dramatically reducing sound levels across the RPM range. On a modified GMC diesel truck, racing on the DHRA circuit, one engine builder found 33 lbs/ft of torque and 13 horsepower at 2,850 RPM. Only a simple change out to the Hushpower from a competing performance muffler was made.
In the racing world, the Hushpower Pro Series Racing Mufflers (Parts 13016101 & 13516101) have been tested and mandated by the United States Auto Club (USAC) for the 2007 USAC Western States Divisions of sprint cars and midget sprints, as well as the C.R.A. sprint car series.
The internal construction of the Pro Series is T409 stainless steel and the outer case is fabricated from rugged 18-gauge aluminized steel. With part numbers available in 3.00, 3.50, 4.00, and 5.00 inch pipe diameters, we have the solution for your needs. Additionally the 3.00 and 3.50 inch models are also available with an integrated turn-down outlet for many racing applications.
The bottom line is that if you want to make more power, quietly, Hushpower Pro Series is the answer.
 
That thing is soooo f**king bad ass! GREAT job on the build man. TOOORRRQUE MONSTER. :D

I know how that goes :rolleyes:, just checking up on the build. After all I blame you and a few others for what's sitting in my shop right now :D. I just couldn't get the Cummins swap out of my head, so when I stumbled upon a 94 whole truck, body vandalized, 2wd with 71k on it, I couldn't say no :D.

71k :D Great score! You can blame me, cause I blame everyone on this site for my disease, wallatitus aka thinning of the wallet:o
 
I've noticed that all the build threads like this I've seen all start with a K5 that had a diesel engine in it. Are there any reasons for this or is it just a coincidence? Is there any major differences with performing a swap on a K5 that originally had a gas engine?

We have emmission testing where I live so it was easier to start with a diesel plus I found a really nice one.
